What is the main ingredient of stomach acid?

The main component of gastric acid is hydrochloric acid, which can corrode food and then be digested and absorbed by the human body. There will be a cell in the bottom of the human stomach, which is called the main cell and has the function of secreting gastric acid. The main component of gastric acid is hydrochloric acid, which also contains pepsin and internal factors. These substances exist in the stomach in liquid form. When food enters the stomach, it will be mixed with food to decompose food and convert its ingredients into nutrients, which is more conducive to human absorption. However, some people will cause abnormal acid secretion due to inflammation or dysfunction. When acid secretion is excessive, it will cause heartburn, acid reflux, heartburn, etc. When acid secretion is too low, food will be due to lack of digestion of acid, thus causing indigestion.
